Infant vision
From Self-sufficiency
The science of infant vision gives a verifiable basis for some practices of pediatric ophthalmology and gathers measurements intended to describe, monitor and predict:
- development of retinal photoreceptor cells
- infant sensitivity to detail, color, contrast, and movement
- binocularity
- eye movements
- refraction
- cognitive processing
By establishing a timeline of visual perception development in "normal" babies and comparing such data with that of babies with visual "abnormalitites" it is hoped to further the understanding of the role of early visual development in the overall visual picture of sensory growth and change.
The newborn’s visual acuity is approximately 20/400, and reaches 20/20 by age 2 years. [1]
